So far as I can tell, no one has been able to hack their duo to allow the use of an advanced slicer such as slic3r or repetier. So my question if I can't hack my board can I replace it with an arduino or one from a DIY kit?

any ideas would be greatly appreciated....my duo is killing me. I paid an extra $170 for a machine that only lets me use XYZware and the "privilege to use only XYZ cartridges"

I was looking at Luc's configuration.h and I couldn't find how to change the number of fans. do you know if this file's default values are 2 extruders and 2 fans?

I would like to give you a heads up that I am very new to working with software. I may ask a couple dumb questions before I finish installing the firmware, so I hope you will humor my lack of knowledge. I would love to learn enough to be useful and help modify the 2.0 duo.
